A 60th Anniversary tribute to one of three classic timepieces released in 1957, this Railmaster, limited to 3,557 pieces, is based on the original antimagnetic watch designed for those working close to electrical fields. It retains the 1957 model's unpretentious style, but is powered by the Master Chronometer 8806 which can resist magnetic fields of up to 15,000 gauss.All Omega watches now supplied with 5 year warranty.
